05 lly

No gear designator (can still see PRND321) no reverse lights when in reverse, when in drive I’m stuck in 3rd. I’ve got no codes on the dash and still have all the power I normally do just 3rd gear only. HELP, I’m going nuts.

Welcome to the forum! Do you have a GOOD code reader? Hard to sort out anything without codes... Sounds like a limp mode, you should be able to reset with a good code reader or disconnect batteries for ~10 minutes.

I don’t have a code reader at all. I did disconnect the batteries and NSBU for a half hour and still no change. I ordered a new NSBU and it will be here Tuesday.

was messing around with the interior fuse panel, pulled 10a ignition fuse and discovered it was blown, out a new one in... voila, back to normal
